Find the angular speed in radians per sec. of the second hand on a clock.
My answer is
1 rpm
=1*2pi radians/1minute(1 rotation = 2pi radians)
=2pi radians/60seconds
=1/30 radians/seconds

It goes 2PI radians in 60 seconds. What happened to the PI?

I forgot to put sorry.
So the correct was 1/30pi radians/seconds
